  * @ignore The test described here is currently disabled on systems that are not
  * x64-based and lack an external NVRAM memory device. In order to re-enable the
  * test, you will need to mount the NVRAM device, which will typically appear as
  * /dev/pmem0, to the directory /mnt/pmem. Once that is done, you can follow the
  * instructions above to create a test directory and remove the ignore tag.
